传入的GameCenter邀请不包含播放器

Question

我正在尝试让我的游戏允许一个设备(iPhone)使用GameCenter邀请朋友玩(iPad)。我使用的是标准/默认的MatchMaker接口。iPhone向iPad发送邀请，后者提供通知。

当我按下这个通知时，iPad的‘player(GKPlayer，didAccept: GKInvite)’例程就会被调用。

  @objc func player(_ playerMe: GKPlayer, didAccept invite: GKInvite) {
    print("\n\n\t\tplayer \(playerMe.displayName)(\(playerMe.playerID)) did accept INVITE sent by \(invite.sender.displayName)(\(invite.sender.playerID))")
    GKMatchmaker.shared().match(for: invite, completionHandler: {(InvitedMatch, error) in

      print("\t\tplayers.count = \(InvitedMatch!.players.count)")

      if error != nil {
        print("INVITE ERROR: \(error.debugDescription)")
      }

      if InvitedMatch != nil {
        print("\t\tSetting current match. (\(InvitedMatch.debugDescription))")
        self.currentMatch = InvitedMatch
        self.currentMatch?.delegate = self
//        self.prepareMatch()
      }
    })
  }

输出：

        player Me(G:25139341913) did accept INVITE sent by ‎“-----”(G:12453976)
        players.count = 0
        Setting current match. (Optional(<GKMatch 0x282d39970 expected count: 1 seqnum: 0
    G:12453976:unknown
reinvitedPlayers:(
)>))

玩家数组为空！难道它不应该至少有邀请者在里面吗？‘expectedPlayerCount’正确地反映了2人matchRequest，其中1个玩家(邀请者)已经是参与者)

任何一端都没有调用“player(GKPlayer，didRequestMatchWithRecipients: GKPlayer)”。

因此，iPad不能访问球员来设置比赛，但是iPhone看到邀请被接受，有2名球员，然后继续。iPhone代码：

  func matchmakerViewController(_ viewController: GKMatchmakerViewController, didFind match: GKMatch) {
    print("\n\n\t\tMATCH FOUND\n\n")
    viewController.dismiss(animated: true, completion: nil)

    GKMatchmaker.shared().stopBrowsingForNearbyPlayers()
    currentMatch = match
    match.delegate = self

    if Globals.gameState?.currentState is StateWaitingForMatch {
      if currentMatch?.expectedPlayerCount == 0 {
        prepareMatch()
      }
    }
  }

那么如何让iPad (邀请函的接收者)看到/包含球员呢？

Answer 1

在player(GKPlayer，invite: GKInvite)方法中，通过

让mmvc = GKMatchmakerViewController(invite: invite!)

然后呈现出来：

viewController.present(mmvc!，动画:真，完成:空)
